The diggbar has been the centre of some discussion since it got implemented by digg a couple of weeks ago. Basically the critizism is based on the fact that digg puts a digg-url on in the url-feild on top in the browser instead of making it the page url. The main argument is that people will link to digg instead of linking to the content website.
My theory is that there are three major voices in the social media debate right now. There are the evangelists, the marketers and then a group I would like to call Dr Data. This presentation tries to tell the story of how these three groups communicate what social media is, what is its value and also how it should be measured.
